Hey folks, Canada's biggest gravel race is the Paris to Ancaster (P2A).  I'm posting to get folks' thoughts on tires for Sunday.  Whether you're riding or not here's the question:
  • The conditions should be quite muddy, due to a lot of rain this week.  There are long stretches on pavement and rail trail which will not be muddy.  
  • I'm trying to choose tires.  I am currently running Vittoria Terreno Mix tires, 700 x 40.  I'm tempted to switch to my 700 x 33 tires (WTB CrossWolf on front, Vittoria Cross XL on back).  
  • The 700 x 40 tires are pretty heavy for race day (500g each).  Not that I'm trying to win, but I'd like to get under 3 hrs for the 70km course.  
  • There's not much rough stuff (rocks, roots, etc.) on the course: it's fairly smooth, as a gravel race goes. 
  • I'm guessing that most of the competitive riders will choose a 700x30, but maybe they'll go up in size for these conditions? 
  • Would I choose the large volume tires to "float" a bit in the muddy sections?  Or should I opt for the lighter and faster tires to get a good time? 
Any opinions welcome!  Thanks, folks,

A little late to the game here..lol  I rode yesterday on 700x40's as it's all I have but if I was to do it again I would have rode something smaller. Small penalty to pay in mud for huge gains everywhere else, I'll go back with 33-35's. This was my first year, I was in wave three and finished in just over three hours.

I swapped out the 700 x 40s for my smaller tires (700 x 32 on the front , 700 x 33 on the back).  I was worried the larger tires would really muck things up, b/c I don't have much clearance left with 40s on.  

Very happy I made the switch. I was fine in the mud and faster everywhere else.  The extra clearance helped purge the mud and the lighter tires were nice to roll with. 

Man--a lot of broken rear derailleurs!

I watched a guys rear derailleur snap off then swing into his wheel!! It was carnage in the last three to five km. I stopped twice to dig the mud out, likely wasted 10 minutes but may have been a savior for my derailleur. Next year I will be back but with different rubber next year. Still did ok rode the third wave and came in 488th.
